This booklet sheds light on nine basic features of the two main sources of Islamic teachings (the Qur’an and the narrations of Prophet Muhammad). It includes a focused discussion on the Islamic moral system, which calls for preserving human rights and strengthening the relationships among humans. It shows how these teachings call upon us to improve ourselves, both inwardly and outwardly, from eighteen different aspects. It should be noted that these moral teachings were revealed from Allah; they are not the result of human work or experiences.
